It's pretty standard to include a huge, muscled stony character on any team that features aliens. You see it all the time. L.E.G.I.O.N. was no different, but it stood out in that Strata was revealed to actually be a female member of her species. Later, she even married another member of the team and had a child, while still being badass.

This actually makes her a particularly notable character, because you don't often see female character getting to play this role on a team. While the fact that she'd very deliberately depicted as asexual is obvious, it's still a cool feature for the team to have.
